Landslide Hazard Map Analysis using Geospatial Technology

Omar Al-kouri

Geospatial technology provides flexibility integrating with various information for studying spatial complex data of evaluation hazard mapping in disaster. GIS-based landslides hazard mapping in the Mukim Hulu Kelang, complimented with the Analytical Hierarchy Process (AHP). Topographical and geological data were collected, processed and constructed into a spatial database using ARC-GIS 9.3. The major outcome of this research is the landslide hazard map with five types of zones (very low risk, low risk, medium risk, high risk and very high risk). Areas with very high risk potential for landslides cover approximate 0.31% of the total area. The result of this study was verified using landslides location over a year obtained from Public Works Department (PWD)
